“If we examine all persons, we will find that everyone has a beginning, but when we approach a person who has no beginning, He is the Supreme Person. That is the definition given in the Brahma-samhita. Ishvarah paramah krishnah: [Bs. 5.1] the Supreme Personality of Godhead is Krishna, the supreme controller; He is without beginning, and He is the beginning of everyone. This definition is found in all Vedic literatures.” (Shrila Prabhupada, Shrimad Bhagavatam, 3.26.3 Purport)
